Outer ear

related to how the nervous system transmits that sound to the brain. Conductive The outer ear gathers sound waves from the environment and funnels them into the ear canal. At the end of the canal, the waves hit the eardrum, causing it to vibrate. Three tiny bones in the middle ear conduct the vibrations from the eardrum to the cochlea (a spiral-shaped chamber that looks a bit like a snail) in the inner ear. If anything interferes with the transfer of sound waves up to this point, the…

hard as I could, plugged one into my left ear, and spun it until it was perfectly fitted in. Then I plugged the other, and did the same to it. That was what the doctor asked me to do. I walked into the classroom, sit down, opened my music folder. The sponges soon expanded, filling up every minute space in my external auditory canal, almost strong enough to make my ears explode. The instruments’ sound volume was then turned down; less music flew into my ears. The earplugs, as though the physical…

sound as the ear drums move from the sound pressure. Then, this vibration is transformed into electrical impulses, which are sent to the brain. The transformation of the electrical impulse occurs inside the outer, the middle and the inner parts of the ears. The outer ear is called the external sound-gathering part of the ear. Its function is to gather sound energy and focuses it on the eardrum. The middle ear, an air-filled chamber serves as an amplifier of vibration. The inner ear is where the…

vibrate. This vibration will spread from molecule to molecule causing sound to travel. 1. What is a wave? A wave is a chain of vibrating molecules. In general, a wave transfers energy from one place to another. 2. Can sound move through outer space? There is matter in outer space, it’s not the vacuum people say it is. It contains a few hydrogen atoms per cubic meter. So, if there is a sound, the sound can travel or move through the matter that is present. There are gases in space…

mixed hearing loss. Conductive hearing loss is due to problems with the ear canal, ear drum, or middle ear and its bones. The causes of this type of hearing loss can include but not limited to fluid in the middle ear from colds, allergies, earwax, and infections. Some of these causes can be treatable with surgery and even antibiotics while some will have to use a hearing aid. Sensorial hearing loss is due to problems of the inner ear and is also known as nerve-related hearing loss. Causes can be…

Focus Objectives 1. Develop at least two (2) complete nursing diagnoses related to medication administration. Impaired Oral Mucous Membrane related to Medication side effects as evidenced by dry mouth and difficulty swallowing. (546) Risk for Aspiration related to impaired swallowing. (67) Impaired Tissue Integrity related to Excess fluid volume as evidenced by damaged tissue surrounding the subcutaneous area. Risk for Infection related to tissue destruction. 2. Identify the six rights of…

Problem Set 7.1 a) Null Hypothesis: Within the 95% confidence interval there is no significant difference between the two-point threshold test disdances among the different areas. Alternate Hypothesis: Within the 95% confidence interval there is a significant difference between the two-point threshold test disdances among the different areas. b) The null hypothesis should be rejected because the p-value is 0 which is lower than 0.05, also because the conifence intervals for the back of the hand…

and becomes harmful to the human ear. How can noise damage our hearing? To understand how NIHL happens, we need to understand how it is that we hear. First, sound waves enter our outer ear then travel through the ear canal into the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to the malleus, incus, and stapes (three tiny bones in the middle ear). Once in the middle ear the vibrations are sent to the cochlea of the inner ear, which is filled with fluid.…

I concluded that tympanoplasty was the perfect intimidating name for such an intimidating procedure. Essentially, the ear is cut halfway off of the body in order to access the inner ear. From there, whatever remains of the eardrum is cut away, the inner ear is filled with gelatin packing, a new eardrum is grafted on, the outer ear is filled with cotton packing, and finally the ear is stitched back on. The next morning, I woke up feeling weak and exhausted. It was 6:00 am on July 11, 2016; I was…

In the ear: custom made, two types, one fills the bowl shaped area of your outer ear and one fills only the lower part (half shell), for mild to severe hearing loss (Mayo Clinic Staff, 2014). Behind the ear: hooks over top of ear and rests behind the ear, has a tube connecting to the hearing aid to a custom earpiece that fits into the ear canal, for all ages and hearing loss (Mayo Clinic Staff, 2014). Receiver in canal or ear: similar to behind the ear except has a speaker or receiver…
